PgCat is a high-performance PostgreSQL connection pooler and load balancer built for modern, distributed systems. Written in Rust, PgCat is designed to efficiently manage database connections across multiple shards and replicas while supporting features like automatic failover, query-based routing, and observability. It works with both single-node and multi-tenant Postgres setups, making it ideal for cloud-native applications that require scale and reliability.

Features

  • Load balancing across Postgres replicas
  • Connection pooling for improved efficiency
  • Sharding support with per-shard configuration
  • Automatic failover and health checks
  • Query routing based on read/write type
  • Built-in metrics and observability tools
